Product Description:

FRP roof fan is the advanced roof ventilation equipment, mainly used in ventilation hotels, restaurants, theaters, office buildings, laboratories, factories, residential and other buildings.

Roof fan with a beautiful shape, compact structure, high strength, light weight, corrosion resistance, aging resistance, low power consumption, low noise, reliable operation, easy installation and maintenance features, the use of a venturi tube entrance test method test, compared with similar products improve the rate of 30%.

According to user needs, I also can produce the same roof fan explosion model and its performance.

I produced the roof fans, with the following features.

High efficiency, low noise: the use of advanced CAD software, designed by the multi-objective optimization. DWT-Ⅰ series machine numbers 12 # -24 # total of eight machine number fans, by changing the speed, angle and leaf-type approach, the expansion of the range of performance parameters to meet the needs of different use conditions, to the fan with the system area with to facilitate the realization of energy-saving and noise reduction.

Smooth operation and long life: small moment of inertia, high dynamic steady precision, smooth operation, and the enterprise requirements of modern standards of the performance indicators were higher than the fan industry standards to ensure that the fan at the leading position in the peer.

Suitable for a wide range: The fans can use the request, made into explosion proof type, suitable for flammable, explosive and corrosive gas forced air ventilation occasions;

After several provinces and Technical Supervision qualified, users can be assured.

Q:What is the broken bridge of aluminum? What are the characteristics?
Waterproof, fireproof, anti-theft performance: broken bridge aluminum doors and windows with a rainwater structure designed to completely separate the rain from the outdoor, watertight in line with national standards; its aluminum alloy material for the metal material, Can be a good solution to the family fire hazard; for anti-theft performance is good, because the broken bridge aluminum composite window prepared a good hardware accessories and senior decorative locks, thieves face it can only helpless.
Q:What is the difference between plastic doors and windows and steel doors and windows?
Through the cutting, welding, etc. made of doors and windows of the frame fan, equipped with sealing tape, tops, hardware and other accessories made of doors and windows, in order to enhance the rigidity of the profile, more than a certain length of the cavity need to add reinforced steel (steel Lining), this kind of doors and windows called plastic doors and windows.
Q:What is the quality of plastic steel profiles in the end?
Quality in general, market acceptance can be, but the price is relatively high.
Q:What is the amount of plastic profiles
For the sliding window, the commonly used fan frame of the European profile, for example, the amount of lap by the window frame ribs, window groove groove and pulley size decision. Usually the ribs, the same size (also has a rib size larger than the groove size), 20 ~ 22mm. Fan groove size minus the pulley height, that is, fan and the next frame of the lap, pulley height is generally 12mm, The amount of lap is 8 ~ 10mm. Industry standard requirements between the frame fan lap uniform, then the fan and the box on the amount of overlap is 8 ~ 10mm.
Q:Bathroom plastic door with what material to do
1 PVC plastic doors and windows 1) In all kinds of building windows, PVC plastic windows in saving energy production profiles, recycling of recycled materials and the use of energy consumption has a prominent advantage in the insulation and energy saving has excellent performance and low cost. 2) In order to increase the rigidity of the window, in the window frame, sash, the tread profile of the force bar, should be based on the strength of the wind pressure design and other requirements to determine what kind of reinforced steel. 3) Coextrusion of UPVC resin with colored polymethyl methacrylate (PMMA) or acrylonitrile-styrene-acrylate copolymer (ASA), as well as coating on white profiles, can be coated with a variety of textures and A variety of surface color decorative effect. In addition, UPVC resin powder is also added to the pigment mixture extrusion of the body dyeing technology. But there are still different views on this technology, it should be particularly careful in the selection, to check the kind of profiles by artificial accelerated aging test after the color changes. It is recommended to coat the color film with the color film to improve its weatherability.
Q:Plastic profile brittle extrusion process unreasonable reasons
Head pressure is insufficient On the one hand and mold design; the other is the proportion of the feed and temperature settings, the pressure is insufficient, the material density is poor, it will become loose tissue plastic brittle phenomenon, then adjust the metering feed speed And extrusion screw speed so that the head pressure control in the 25Mpa-35Mpa between.
Q:What belongs to plastic profiles
Plastic Profile A: Impact modifier Plastic profiles, such as without impact modifier, plastic profiles will be very brittle, slightly collision, easy to break. Plastic profiles used in the production of anti-impact agent modifier mainly by the following three categories: chlorinated polyethylene, polyacrylates, ethylene - vinyl acetate copolymer. Plastic profile additive two: heat stabilizer Plastic profile is a thermosensitive plastic, so in the production and processing of plastic profiles, heat stabilizer is essential. The metal salt in the heat stabilizer absorbs the HCL from the PVC, so it can delay the decomposition rate of the plastic and prolong the decomposition time. The most commonly used in the production of plastic profiles is the compound lead salt, which has high thermal stability and low cost. Plastic profile additives three: lubricant The main role of the lubricant is to reduce the polymer and processing equipment and polymer molecules between the internal friction between the friction caused by excessive heat caused by resin degradation, improve the efficiency of heat stabilizer.
Q:How plastic embossed profiles are made
Plastic processing is a complex process, generally divided into the following main processing methods:
Q:The state of high-rise residential building doors and windows materials are not allowed to use steel profiles are expressly provided?
Allows the use of steel profiles. The provisions of the doors and windows with the number of layers does not matter. Now energy-saving requirements, no matter what material, as long as the energy-saving requirements on the line. Aluminum need to use heat type, more expensive, so the use of steel is more common.
Q:Fence material outside the plastic inside is iron or steel this material called
Plastic steel profiles are made of polyvinyl chloride (PVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, UV absorbers, etc., by extrusion of the profile.
